RRE1648

Reference Radiographs are nondestructive testing standards universally accepted because of their high reliability in accept-reject actions.

The reference radiographs illustrate various types and severity levels of discontinuities in aluminum fusion welds that may be revealed by radiographic examination. These reference radiographs do not specify the acceptable level of these discontinuities; rather they provide a visual reference for communicating the acceptable level. The reference radiographs consist of a set of eight plates (8.5 x 11 (22 by 28 cm)), covering base material up to and including 0.75 in (19 mm) in thickness.

A copy of the current ASTM standard is included with the purchase of these reference radiographs.
